I've said before that since the coolers included with retail CPUs are both quiet and effective at stock clock speeds, overclocking is the only reason anyone should buy a third party CPU cooler. Well, this isn't strictly true: not all third party CPU coolers are designed to handle ultra-high overclocks in massive tower systems; sometimes, what you need is a cooler that is more effective than the retail cooler in specific situations, such as the tight confines of a micro-ATX or HTPC case. When airflow's at a premium, a properly designed cooler that can fit into a tight space can be a big help. Benchmark Reviews looks at Cooler Master's new GeminII S524 cooler, which is designed for just such applications.
